What are the symptoms of testicle cancer?

What are the symptoms of testicle cancer?

Painless mass.: Testicular cancer usually presents as a painless mass in the scrotum. Because there is often no pain, many unfortunately delay evaluation. As the mass enlarges, there may be discomfort or a sensation of fullness in the scrotum, seen in 30-40%. 10% experience acute pain. If the cancer spreads, symptoms of more advanced disease such as neck mass, back pain, bone pain, or cough may result. ...Read more

The testicles are the two oval male gonads, or reproductive glands, located in the scrotum. The seminiferous tubules of the testis are the site of spermatogenesis and its leydig cells secrete testosterone. The term testicles is synonymous with testes or gonads. The singular form is ...Read more

What is the difference between seminoma and nonseminoma cancer of the testicles?

What is the difference between seminoma and nonseminoma cancer of the testicles?

Different tumors: Over 90% of testis tumors are germ cell tumors which are seminoma, non-seminoma or mixed depending on the type of malignant cell. Classic seminoma is the most common testis tumor in adults. Almost all testis tumors are initially treated by surgical removal (orchiectomy). Then, based on the type of tumor and stage (aggressive characteristics, spread to lymph nodes) determines next treatment. ...Read more

Post op seminoma, in r testicle. Pet scan done for suspecious nodes. Pet scan result shows negative for any abnormalility. This means no seminoma?

Post op seminoma, in r testicle.  Pet scan done for suspecious nodes. Pet scan result shows negative for any abnormalility. This means no seminoma?

Surveillance: A negative pet scan means there is no accumulation of cancer cells large enough to be discernible by the pet scanner. There is a resolution limit of about 7mm in size to be seen, some are better now. I am not trying to scare you, but your doctor i'm sure will continue to caution you and continue surveillance for a period of time safe to say you are cancer-free. ...Read more

Undecended right testicle and found seminoma, azoospermia in two samples with in 3 weeks. Left testicle normal in ultrasound scan. Am i sterile?

Undecended right testicle and found seminoma, azoospermia in two samples with in 3 weeks. Left testicle normal in ultrasound scan. Am i sterile?

Possibly: Sorry to hear about your recent diagnosis. Good news is that seminoma and testicular cancer in general almost always curable nowadays especially in early stages. Assuming your semen collections were correctly obtained and tested, complete absence of sperm (azoospermia) implies sterility. Would certainly recommend that this be evaluated further to determine cause especially in view of normal us. ...Read more

Operated undecended testicle showed tumor cells . Enlarged paraaortic lymph node in ct. But tumor markers normal. High alt(67). Is it still seminoma?

Operated undecended testicle showed tumor cells . Enlarged paraaortic lymph node in ct. But tumor markers normal. High alt(67). Is it still seminoma?

In situ?: The diagnosis of seminoma is made on examination of tissue by the pathologist; tumor markers and imaging are ancillary studies. An undescended testis often has premalignant cells lining the tubules; these are not yet cancer and if gone will not be troublesome. If you were told there was indeed an actual seminoma, that's a different story & you may require followup such as biopsy of the node. ...Read more

Right testicle operated showed seminoma. Ct showed enlarged paraaortic lymph node. Does this means metastatis or due to surgery?

Right testicle operated showed seminoma. Ct showed enlarged paraaortic lymph node. Does this means metastatis or due to surgery?

Usually metastasis: Seminoma can occur in testes or the mediastinum as the primary tumor, it is classified as one of the germ cell tumors. If there is regional paraaortic node histooogic involvement if usually is metastasis. Chemotherapy and/or radiation has very good cure rate even with metastases. At surgery they sample the regional nodes for involvement to determine best treatment for patient. ...Read more

Seminoma in post op intra abdominal r testicle (undcnd), l testicle normal in ultrasound scan, azoospermia in semen analysis. Can i father in future?

More info: If u got chemo, it may take a few years to regenerate sperm. Also, seminoma is often treated with radiation but they likely shielded your left testis. I don't have enough information to predict how you're going to do. ...Read more

Different Exam: An inguinal hernia is a hole in the groin muscles thru which a sac may protrude through, occasionally extending into the scrotal sac, next to the testicle. A testicular cancer presents as a growth within the testicle. These two abnormalities can be easily differentiated from one another by a careful physician examination. ...Read more

In testicular cancer, how often is there not a palpable mass ON the testicle and the cancer is INSIDE the testicle.Difference between ON and IN common?

In testicular cancer, how often is there not a palpable mass ON the testicle and the cancer is INSIDE the testicle.Difference between ON and IN common?

Not meaningful diff.: This may be a semantic distinction more than a biological one. The cancer arises within the testicle, but may extend to the surface of that organ and bulge away from its surface. Thus, the tumor may FEEL to be on the testicle even though it has arisen from within it. Not all testicular cancer extends to the surface of the testicle. Palpation is clearly inferior to ultrasound examination here. ...Read more

Is there any relation between azoospermia and seminoma cancer?

Low sperm counts: Are common in men with testis cancer, seminoma and non-seminoma. Reason is not clear. Some believe there is a developmental issue, undescended testis also at higher risk, others blame anesthetics. Truth be known, we do not know. ...Read more
